So two questions: why isn't -f the default? And is /sys/slab guaranteed to be a stable and permanent interface if the SLAB implementation ever gets ripped out? If so, maybe this should go into util-linux-ng? I am aa bit concerned about the lack of atomicity of /sys/slab, but this is a heck of a lot better of many kernel drivers or subsystems which use /sys and the completely punt on any kind of userspace utility, forcing users to type crazy things like
echo 5 > /sys/bus/pci/drivers/iwl4965/*/power_level
